Letters Patent No. 112,114, dated February 28, 1871.

IMPROVEMENT IN SAWlNG-MACHINES.

The Schedule referred to in these Letters Patent and making pai't of the same.

To all whom it ma@ concern.:

Be it known that I, N. H. BOLTON, of Omro, in the county of Winnebago and State of Wisconsin,

have invented a new and improved sawing-Machine;V

and I do hereby declare that the following is a'full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

rlhis invention relates to improvements in sawingmachines, whereby it is designed to provide a ma'- chine for sawing the .spalts or waste-blocks from shingle-machines into shingles in a manner to utilize the whole ofwthe timber, ot' which a considerable percentage is now wasted, owingto the fact that in most shingle-machines the stock cannot be wholly Worked up, theholdingdogs being in the way of thesaws;

Figure I represents a side elevation of my improved machine, and

Figure 2 represents a plan view of the same.

Similar letters of ireference indicate corresponding parts.

A represents a circular saw, working'on a bench, B, in a horizontal position in a manner common to sawing-machines.

G represents a'carriage arranged to move along one side of the saw on the parallel ways D, Vand so connected to the said ways as to work equally well horizontally or vertically. A E is a timber-restvadjnstably connected to the carriage perpendicnlarly thereto, the end nearest th'e said mandrel being adjusted closely to the saw, while the other end recedes about the thickness ofthe thick end of the shingles, and is provided with a vertical 'stop F.

thrust forward by an inclined guide, I, fixed on one of the ways, D, against which the outer end of the said discharger strikes just previous to the end of the .return movement of the carriage.

The discharger is 'drawn back by a coiled spring, KQ

The spalts or waste blocks from the shingle-machine, which are commonly thick enough to make two or three shingles, are set edgewise on `the carriage in front of the support E, in advance of the stop F, and there held by 4one hand while the carriage is moved forward against the saw and a shingle cut therefrom. 1f the block be thick enough for two shingles one cutting completes the operation, the cutting being diagonally through'the block, the outer shingle falling ou the part L of a tilting-table pivoted near the axis ot the saw, and being delivered thereby with the shingles discharged from the carriage.

It' the piece to be sawed will make but one shingle the table is to be tipped from the operator, which carries the cull or shim olf back of the machine; but if' the piece is large enough for another shingle the table is turned toward the operator, andthe piece slides back to he re-sawed.

The turning ofthe tablev is accomplished by the operator while in the act ot' sawing a shingle, by being touched with the next piece to` be sawed.

N represents an adjustable rest, secured to the guide-rail next the "saw in a manner to be adjusted to or from the saw. 'lhe block rests on this support, as well as on the carriage, while being fed up the saw.

- 'lhis adjustable rest also supports an adjustable sawgauge, O, for guiding the periphery of the saw.

Having thus described my invention,

What I claimas new, and desire to secure by Letters Patent, is-

The carriage C, adj ustble rest E E', spring-retracted discharger H, inclined guide I, and saw-gauge O, all combined as described, andfoperated in connection with the saw, for the purpose specified.
